Textbook Question
Chapter 39, Problem 4TYU
How may a plant respond to severe heat stress?
(A) by reorienting leaves to increase evaporative cooling
(B) by creating air tubes for ventilation
(C) by producing heat-shock proteins, which may protect the plant's proteins from denaturing
(D) by increasing the proportion of unsaturated fatty acids in cell membranes, reducing their fluidity
